如何为iOS构建ohNet？

Question

我正在尝试从openhome.org构建ohNet UPnP堆栈，以便在iPhone和iPhoneSimulator上执行。我曾在网络上的不同地方看到，iOS上有一个端口，并且实际上在Makefile中有一些对iOS构建的引用。在$ DEVROOT和$ SDKROOT路径进行一定的编辑后，我可以编译很多的来源，但生成的错误停止：

我不明白为什么编译过程要建立ohNetDll这个平台，也不知道如何退出该部分/目标。动态库不支持iOS应用程序，当然也不是Windows本机的dll。

如果您已经在iOS上构建/移植/使用过ohNet，请告知如何操作？我想在ohNet论坛上发布这个问题，但我无法注册（因为我没有提交安全问题，即使在表单上没有地方这样做！）。

源，文档和API指南都会寻求ohNet非常有前途的，所以我希望你能劝...

“的$ DEVROOT的一些编辑和$ SDKROOT路径之后，我可以编译 很多来源...“

对于iPhoneOS平台，请设置以下环境变量。

export ROOTDIR="/Applications/Xcode.app/Contents/Developer" 
export PLATFORM="iPhoneOS" 
export MAX_VERSION="5.1" 
export DEVROOT=${ROOTDIR}/Platforms/${PLATFORM}.platform/Developer 
export SDKROOT=${DEVROOT}/SDKs/${PLATFORM}${MAX_VERSION}.sdk 

然后，在源的根目录下，文件“Makefile”文件中，找到以下部分，并确保它看起来相同的，因为这一个：

ifeq ($(MACHINE), Darwin) 
ifeq ($(mac-arm),1) 
    # Darwin, ARM -> iOS 
    platform ?= iOS 
    linkopts_ohNet =  
    devroot=$(DEVROOT) 
    sdkroot=$(SDKROOT) 
    platform_cflags = -I$(sdkroot)/usr/lib/gcc/arm-apple-darwin10/4.2.1/include/ -I$(sdkroot)/usr/include/ -I/usr/bin/arm-apple-darwin10-gcc -miphoneos-version-min=2.2 -pipe -no-cpp-precomp -isysroot $(sdkroot) -DPLATFORM_MACOSX_GNU -DPLATFORM_IOS -I$(sdkroot)/usr/include/c++/4.2.1/armv6-apple-darwin10/ 
    # It seems a bit weird that iOS uses a sub-dir of Build/Obj/Mac, is that deliberate? --AW 
    osbuilddir = Mac/arm 
    objdir = Build/Obj/Mac/arm/$(build_dir)/ 
    platform_linkflags = -L$(sdkroot)/usr/lib/ -arch armv7 -L$(sdkroot)/usr/lib/system 
    compiler = $(devroot)/usr/bin/llvm-gcc-4.2 -arch armv7 -isysroot $(SDKROOT) -o $(objdir) 
    # No support for linking Shared Objects for ARM MAC 
    # link = $(devroot)/usr/bin/llvm-gcc-4.2 -pthread -Wl $(platform_linkflags) 
    ar = $(devroot)/usr/bin/ar rc $(objdir) 
    native_only = yes 

要点这里：

1. $ DEVROOT和$ SDKROOT对于您的iOS SDK版本是正确的。
2. 变量$ native_only被设置为yes。这避免了在Mac主机上尝试（并且不可避免地失败）建立ohNetDll时的错误和提早退出。

然后，在终端上，在源根目录（即含有生成文件的一个）类型：

make mac-arm=1 

希望这有助于...
